Tomorrow’s “Hiring Our Heroes” job fair at Camp Pendleton isn’t for the one in uniform.

This time, military spouses are the focus of the U.S. Chamber of Commerce event.

They often sacrifice employment opportunities or career momentum to support a husband's or wife’s military career, which demands frequent moves and long separations.

Spouses of active duty, guard, reserves and military retirees are invited to meet more than 35 employers expected to participate – including some of America's biggest as well as dozens of small companies with regional jobs available for all experience levels.

Since its launch in March 2011, Hiring Our Heroes has helped more than 100,000 veterans and military spouses find meaningful employment, the chamber announced. More than 18,400 hires came from more than 500 job fairs nationwide like the one at Camp Pendleton.

An additional 90,000 veterans and military spouses have been hired as a part of Hiring 500,000 Heroes, a national campaign by the U.S. Chamber, National Chamber Foundation and Capital One to engage businesses in committing to hire half a million before 2015. So far, more than 900 businesses of all sizes have pledged to hire 221,000 toward this goal.
